Probably caused by : atikvmag.dll

Whilst running WAR.EXE (game)

Confirm your Video card drivers are up to date
And confirm all updates (if any) are installed on war.exe

atikvmag.dll. Description: Virtual Command And Memory Manager

thanks Kim for the quick reply

Well I was using Catalyst.8.7 driver when the restart happen, and just now I took your advice and update it to 8.8 (latest version). Hopefully that would fix the restarting issue. ^^;
